# Download OpenIPC for V39 wget https://github.com/OpenIPC/firmware/releases/download/latest/openipc.v39-*-nor-flash.bin flashrom -p ch341a_spi -w openipc.v39.bin Then configure RTSP, MQTT, etc. via web interface. | Problem | Solution | |---------|----------| | Bricked camera (no boot) | Re-flash via SPI programmer + original backup | | RTSP not working | Check if rtsp_server binary exists; try strace to see missing libs | | WiFi not connecting | Use iwconfig manually; check antenna connection | | UART no output | Swap TX/RX; check baud rate (115200 or 57600) | 10. Conclusion The Mjsxj10cm firmware is modifiable despite lacking official support. By dumping, extracting, and repacking the SquashFS root, one can remove cloud dependencies, enable RTSP/telnet, and secure the device. For long-term use, OpenIPC provides a cleaner, maintainable alternative.
